I’ve been diving deep into the latest research on three popular incretin-based therapies—Semaglutide, Tirzepatide, and Retrutide—and trying to figure out which one offers the best bang for your buck, especially if you’re mindful of cost.
Here’s what I’ve gathered so far:
Semaglutide, marketed under names like Ozempic and Wegovy, is a GLP-1 receptor agonist that’s been revolutionary for weight loss and glycemic control. Clinical trials show it typically induces weight loss around 10-15% of body weight over 68 weeks. Its dosing is relatively low—usually maxing out at 1 to 2 mg weekly—which means even though its weight loss results might be slightly less dramatic than the newer compounds, the amount you need is smaller, making it more cost-effective. Plus, its safety profile and side effect spectrum are well documented.
Tirzepatide is a dual GIP and GLP-1 receptor agonist, a bit of a “next-gen” drug that targets multiple pathways. Recent studies, such as those published in The New England Journal of Medicine (2022), have shown it can achieve weight loss upwards of 20% or more—significantly higher than Semaglutide in comparable timelines. However, dosing can go as high as 12-15 mg weekly, which increases both cost and potential side effects like nausea or GI discomfort. It’s a more complex molecule and thus pricier, but its multi-receptor action seems to confer enhanced efficacy.
Retrutide is an emerging therapy, also a multi-agonist targeting GLP-1, GIP, and glucagon receptors. Early data, including recent phase 2 trials, suggest it might outperform both Semaglutide and Tirzepatide in terms of weight loss and metabolic improvements. However, the doses required tend to be higher, similar to Tirzepatide, which again affects the cost and duration of treatment. It’s still relatively new, so long-term safety data and widespread availability are limited.
Bottom line: Semaglutide remains a solid, well-studied, and more affordable option for most people. Tirzepatide offers greater efficacy but at a higher price and dosing burden. Retrutide could be the next frontier but still needs more real-world data.
Would love to hear your thoughts or any personal experiences! Have you tried any of these? Do you think the extra cost of Tirzepatide or Retrutide is justified for their added benefits?

1. Semaglutide

2. Tirzepatide

Recent studies, such as those published in The New England Journal of Medicine (2022), have shown it can achieve weight loss upwards of 20% or more—significantly higher than Semaglutide in comparable timelines.

Retrutide is an emerging therapy, also a multi-agonist targeting GLP-1, GIP, and glucagon receptors.

However, the doses required tend to be higher, similar to Tirzepatide, which again affects the cost and duration of treatment. It’s still relatively new, so long-term safety data and widespread availability are limited.
So, which one should you choose?
- If budget is your top concern, Semaglutide is currently the most accessible and cost-effective option, especially since you need less drug per dose. Its weight loss effects, while modest compared to newer agents, are still substantial and clinically meaningful.
- If maximizing weight loss is your priority and cost is less of a concern, Tirzepatide’s dual agonist profile offers superior results, but expect to pay a premium and tolerate potentially more side effects.
- Retrutide looks very promising and could be a future game-changer, but it’s still early days, and access/cost remain barriers.
A few other considerations:
- Side effect profiles: GLP-1 agonists often cause nausea, vomiting, and GI discomfort, especially when starting or ramping up doses. Tirzepatide and Retrutide might have more intense side effects due to their multi-receptor action.
- Duration and dosing convenience: Lower doses like Semaglutide’s translate to longer-lasting supply per vial, which can be more convenient and cost-saving.
- Overall metabolic benefits: Beyond weight loss, these drugs improve insulin sensitivity, reduce appetite, and may have cardiovascular benefits—important factors to consider.
Bottom line: Semaglutide remains a solid, well-studied, and more affordable option for most people. Tirzepatide offers greater efficacy but at a higher price and dosing burden. Retrutide could be the next frontier but still needs more real-world data.
